Abstract: In particular, the mutation
N88D, lethal for the wild-type
protease, restored the wild-type catalytic efficiency when combined with the highly deleterious mutation
D30N.
Abstract: When a second random mutagenesis library was constructed from an HIV-1
protease carrying a highly deleterious single mutation (
D30N), a higher proportion of mutations with neutral or beneficial effect were found, 26% and 9%, respectively.
